Property taxes in New Jersey, on average, have more than doubled in the past 20 years. But that alone is not the troubling part of the story.

By and large, the Garden State's median income has not kept pace with its blistering property tax bills, among the highest in the nation, according to a USA TODAY NETWORK New Jersey analysis of New Jersey property tax and U.S. Census Bureau income data.

Between 1998 and 2017, New Jersey's average property tax bill has increased from $4,119 to $8,690.

But that 1998 property tax bill represented about 7.5 percent of New Jersey's median income, which was $55,146 in 1999. Fast forward 20 years, the state's average property tax ate up about 11.4 percent of the median income, which was $76,475.

The Network's analysis found a situation that appears to equally hit rich and poor towns, urban and rural: New Jersey's property tax bills are sucking up a larger portion of residents paychecks.

The analysis found only a handful of towns saw their incomes increase at a rate higher than their tax bills in the past 20 years.
